SMS QR Codes: Pre-Fill a Text Message with a Scan

How it works

This type encodes an SMS link with your phone number and, optionally, pre-filled message text. Scanning it opens the phone's default messaging app with everything ready to go — the person reviews it and taps send, or edits the text first. Nothing sends without them confirming.

Pre-filled text is the whole point

The real value here is the message text, not just the number. A pre-filled 'JOIN' or 'START' keyword is exactly how SMS opt-in marketing and two-way texting services work — the QR code guarantees the exact keyword arrives correctly instead of relying on someone typing it themselves and getting it wrong.

Common uses

SMS marketing opt-ins at retail counters and events, where a keyword text subscribes someone to updates. Quick contact for services that operate primarily over text rather than phone calls or email. Contest and giveaway entries that ask for a specific text keyword to participate.

Generate your SMS QR code

Enter your number and, if you want one, the exact message text above. Test-scan it yourself first to confirm the message appears exactly as intended before it goes out on printed materials.
